At third, here’s a comparison of answers to a question about rebaptism. One is from a paedobaptist (one who baptizes infants) and one from a credobaptist (one who baptizes only believers). There are a lot of good reasons not to be a paedobaptist and this article exposes many of them. The credobaptist answer is a good one. By the way, you should remember that many paedobaptists don’t believe that babies are saved when they are baptized sprinkled (which makes me all the more curious as to why do it). Presbyterians who baptize infants do so for a different reason than Catholics who baptize infants. Please don’t confuse them. Presbyterians are our brothers, even if they are disobedient to the command to baptize.
